How do I find the amplitude and period of f(θ)=2Sin2θ?
I know that the amplitude is 2 but I'm not sure how to find the period or if there even is one

You are correct the amplitude is 2, the coefficient of the sine function. All sine functions have periods as well, and this one is π. To find the period of a sine (and cosine) function, divide 2π by the coefficient of θ: 2π / 2 = π.
